GAS HEATER.

Application led February 2, 1922. Serial No. 533,652.

yTo aZZ whom t may concern:

Beit known that I, HUBERT R. IIUM- rI-rnnr, a citizen of the UnitedStates, residing at Kalamazoo, county of Kalamazoo, State of lidichigan, have invented certain new and useful Improvements in Gas Heaters, of which therfollowing is a specification.

This invention relates to improvements in gas heaters.

The main object of this invention is to provide an improved gas heater in which the burner may be adjusted into operative posi tion in the hegter or withdrawn therefromV as an operative unit for purposesl of demonstration, adjustment and the like.

`Further objects, andv objects pertaining to details and economies of construction and ope-ration will definitely appear from the detailed description to follow.

I accomplish the objects ofv my invention by the devices and mean-s .described in the following specification. rIhe invention is clearly defined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated innthe accompanying drawingsforming a part .of this application in which:

Fig. I is a front elevation of my improved gas heater with parts broken away to show structural details, the burner being shown in operative position in the frame by full lines and in its retracted position by dotted lines.

--FigfII is a detail rear elevation.

Fig. III is an.enlargeddetail vertical section onA a line corresponding to line 3-3 of Fig. I.

Fig. IV is a det-ail horizont-al section on .l a line corresponding to line 1 -Ji of Fig. I

showing details of the positioning stop within the frame.

Fig. V is a detail vertical section on a line corresponding to line 5-5 of Fig. III

showing the relation of the burner to other parts when adjusted to operative position within the frame. l

In the drawings the sectional views are taken looking in t-he direction of the little 'arrows at the ends of the section lines and similar numerals of reference refer to similar parts throughout the several views.

Referring to the drawings, 1 represents the mam casing-like housing and 2 a supporting plate mounted therein. back arranged upon the supporting plate and l are the tubular foraminous radiating o elements arranged upon the supporting plate in front of the fire'back and in-alinement with the openings 5 of the supporting plate. i

I provide a burner which, inthe structure illustrated, comprises a pluralityA of burner tubes 6 having burner tips 7 adapted to deliver through the openings 5 into the bases i pins 12 extending transversely of the burner bodyand riding upon the top of the ways. The outer ends of the ways are supported by the leg 13. 1

A stop 14 is provided within the frame to coact with the inner end of the burner body positioning the burner with its tips in alinernent with the holes 5. Avhandle 15 is pro vided for retracting and pushing the burner into the frame. rIhe gas supply con` nection 16 is flexible so that the burners are operative when adjusted into the frame orv withdrawn therefrom, thus enabling inspection and tests of the flame or other tests of the burner and adjustment thereof when retracted and also the demonstration of itsY 3 is the firei Sil ments as I have embodied them in practice. My improvements are, however, adaptable and desirable tor use in other relations and I desire to be understood as claiming them broadly within the scope oit the appended claims as well as speciiically in the embodiment illustrated.

Having thus described my invention what I claim as new and desire to secure by Letters Pate-nt is:
